Abstract

Methionine is an essential sulfur amino acid and appears as first limiting in poultry nutrition. The sources of this amino acid found in an industrial scale in the market today are: DL- 2-amino-4-methylthio butanoic acid (DLM) and DL-2-hydroxy-4 (methyl) butanoic acid, known as methionine hydroxy analog acid free (MHA-AL). Bio-efficiency values was obtained by testing dose-response using exponential models to explain the animal€™s responses to the sources of methionine. It is not only the composition of the basal diet would influence the efficiency of the use of MHA-AL, but the differences in dietary levels of methionine and the total sulfur amino acids contained in the basal diet. The effects on the performance in diets for broilers and laying hens supplemented with this already healthy amino acid consolidated. This review aimed to discuss the use of DL-methionine (DLM) and methionine hydroxy analog free acid (MHA-AL) as a source of methionine for broilers and layers based on experimental data and technical reported in scientific literature.
